All data are in the unit m⁻¹. The time stamp is related to the measuring cycle of the DMPS, which was set for an hour. Each of the size bins was measured for 4 minutes. The smallest (10 nm) and the largest (504 nm) channels were excluded. The dataset was corrected according to Bond et al. (1999). Instrumentation: From Centre for Atmospheric Science, University of Manchester — [MAAP and PSAP](http://www.cas.manchester.ac.uk/restools/instruments/aerosol/maap/) and [DMPS](http://www.cas.manchester.ac.uk/restools/instruments/aerosol/differential/). The method and structure of the experiment is explained in more detail by Tunved et al. (2020). During the measurement period a fire event happened in Täby, approx. 5 km north of Stockholm University. The wind transported the plume directly to our measurements: 2019-01-24 23:54 (start of the fire) until the following early morning hours 2019-01-25 08:50.
